++Meets NINCDS/ADRDA criteria for probable Alzheimer's disease++Taking stable dose of an acetylcholinesterase inhibitor (donepezil or rivastigmine) for at least 90 days prior to screening++Mini-Mental Status Examination (MMSE) total score of 12 to 24; Cornell Scale for Depression in Dementia (CSDD) score of 10 or less; Modified Hachinski Ischemic Scale (MHIS) score of 4 or less++Good general health, based on results of medical history, physical examination, vital signs, laboratory profile, and electrocardiogram++Caregiver who will provide support, ensure compliance with study medication and procedures, and provide accurate information about the subject's status during the study

++Subject has taken galantamine or memantine within 60 days prior to screening++Clinically significant abnormal laboratory values at screening++History of any significant neurologic disease other than Alzheimer's disease, including Parkinson's disease, multi-infarct or vascular dementia, Huntington's disease, normal pressure hydrocephalus, progressive supranuclear palsy, multiple sclerosis, seizures++Mental retardation++History of significant head trauma followed by persistent neurologic deficits or known structural brain abnormalities++Clinically significant uncontrolled medical or psychiatric illness.

This is a Phase II study designed to evaluate the efficacy and safety of ABT-126 in older adults with mild to moderate Alzheimer's disease who are taking stable doses of acetylcholinesterase inhibitors. Participants will be randomized to receive one of two ABT-126 doses or a placebo for a 24-week treatment period. Participants in this study may be eligible to take part in a related extension study; see NCT01690195 in for details.
